WATER-DISGI-IAR-GING DEVICE.

Application filed Jul 5 ()ur invention relates to a rotatable nozzle forwashing and cleansing apparatus in wiich the water streams are spreadover relatively large areas or surfaces. In this class of apparatus thewater streams are discharged under pressure from one or more conduitswithin the cabinet and these streams, it delivered in a direct axialline would impinge only on a limited area of the surface and the removalof the adherent matter would depend to a large extent on the possibilityor chance of some of the water spreading into the vicinity of that partout the surface to which the adherent matter happened to be attached.

In the case of our present invention we propose to provide the dischargeoutlets of the pipes with rotary devices, that will change the directionand shape of the water streams and impart to them a rotary motion in adirection angularly to that of their discharge from the conduits, andscatter this water with direct force against the surfaces to becleansed.

in the preferred construction we use one or more revolubly adjustabledischarge pipes each fitted with a plurality of discharge nozzles forsimultaneously delivering a corresponding number of water streams underpressure. Each. of these discharge nozzles is formed with a plurality ofrelatively small discharge apertures and is provided with an axial pinon which is revolubly mounted a spirally formed spinner or turbinehaving a disk shaped member at its outer end consisting of a pluralityof segments each set at an angle to the plane of rotation. The waterdischarged through the nozzle apertures, impinging on the spinner orturbine, sets it in motion and coming into contact with the disk shapedmemher is spread or scattered in a sheet like form angularly to thedirection of the discharge through the perforations. The dischargepressure of the water streams through the nozzle outlets causes thespinner or turbine and the disk shaped member to revolve at acomparatively high rate of speed and impel the water with a considerableforce against the objects in its path.

be cleansed are placed in racks, baskets, or trays, with oneor moredischarge pipes above and below each rack, etcetera, and these pipes areset for the direct discharge of the water against their contents, and asthe pipes revolve, sweep or spread the water over the entire surfaces ofthe dishes at diiterent angles of impingement.

Like characters 01" reterence refer to like parts throughout thespecification and drawings.

The discharge pipe 1 is fitted with a plurality of nozzles for theoutlet of the water streams under pressure. Each of these nozzlescomprises a cap 3 having a plurality of diminutive orifices or outletsat formed concentrically about its axis. Extending axially from the cap3 is a pin 5 and rotatable on the pin 5 is a spinner or turbine 6 havingspirally formed vanes 7 against which the water streams from the outlets4L impinge.

Overlying the outer end of the spinner or turbine 6 is a disk likemember 8 composed of a. plurality of segments 9 each set at an angle tothe plane of rotation. The segments are formed by a plurality of cutsextending radially inward from the periphcry and the se ments of thedisc are curved outwardly from the turbine on one side and inwardlytowards the turbine on the other side, the adjacent segments being soarranged as to allow the water from the turbine being discharged betweenthem for scattering the water in a circular direction and imparting toit depth gradually increasing from the center of rotation to the placeof impact. The disk-like member 8 throws the water in a sheet-like formand this water sheet has, in addition to its circular plane, a depth orthickness that increases gradually from the center of rotation to theplace of impact. This depth h'a'sthe effect of subjecting the entireface or the dish to the force of the discharg and results in theadhering substances being forcibly removed The greater the angle of thesegments to the plane of rotation the greater will be the depth of thewater sheet scattered by the disk The water flowing through the outlets4 impinging on the vanes 7 revolves the spinners or turbines 6 at aspeed corresponding to the discharge pressure and coming into Contactwith the disk 8 is converted from a streain i ito a'slieet like form,The revolution of the inclined segments scatters the water at an angleto the discharge through the outlets and spreads itover a considerablecirculararea with a force corresponding to that of its discharge, andthe revoliible adjustment of the water pipe or conduit changes the anglethe direct force of the water as the pipe orconduit revolves.

Haying thus fully-described our invention, what we claimas new anddesire to secure by LettersPatent" is A water discharging devicecomprising a nozzle having a plur'ality of small apertures formedconcentrically about its axis, a turbine mounted on the nozzle axiallyabove and adapted to be rotated by the impulse of water from saidapertures, said turbine having a disc-shaped member at its outer endprovided with a plurality of cuts extending radially inward from theperiph ery forming segments, the segments of the Dated at the said cityof- Toronto, this 45 30 h d y t May,'A.
